M8 has a NA car that has dyno'ed multiple times over 200. Listen to him everyone. He is a true friend and an objective tester of aftermarket parts. Like most of us he doesn't like BS.
RP you are a smart guy, I think you just didn't word your response correctly< " A cat has no affect ---as long as you have a cat"? Implied that it is only for visual inspection? Man----- uh ummmmm-- crossed eyed stare at computer screen. Trying to open something up?.Anyway have to get back to the football game!

The header leaves for the machine shop this week and hopefully will get turned around fairly quick. I'll have to send a stock manifold too for reference so I'll have to get one from Mazmart.
My goal here is to have a header that will function with stock components or a hiflow cat and still have clean tailpipe emissions. It is a fact that at this time, cars from 1 and in some states up to 3 yrs old are only tested visually and through the OBD DLC port. That being said, after a few years they will be dyno tested for tailpipe emissions by 1 of 2 types of test. The method varies from state to state and some states like Florida don't test at all.

so when are we getting an actually dyno of this header to see really how much power its producing

rotarygod

Without air. Forgot about that! Assumed it still had that built into it. Yes, that would probably be important. On past rotaries you did need both air and a cat to pass. The headers on older rotaries also didn't effect whether there was air supplied or not but it did change where. Depending on the load the exhaust could receive air from the air pump at the exhaust port or at the cat. A header would block off the exhaust port air injection location but still left the cat to receive air. The Renesis however doesn't always run the air pump full time as the older ones did so then again maybe it isn't as important. The side exhaust port configuration does do alot towards reducing the emissions.

Why not use my time for something constructive?! Why the ******* attitude?

QBallz

^ Didn't someone pass emissions with a cat replacement tube? Also from what I understand the Renesis produces virtually no emissions because the side port design.

Not really meant to be an ******* attitude or flame. Bottom line is that all of this stuff is NEW to all of us as it is the first NEW rotary configuration any of us have seen in 9years. Things have changed, some work in similar ways and some don't. We are ALL learning as we go just like when all of the other rotary cars were new to us. The FI issue on the 8 reminds me of the early RX7 days with RAJAY turbo kits
and later Cartech. People were trying new things and some worked better than others but NO ONE PERSON knew everything then as now. Everyone brings something to the table but because this is a worldwide forum, it is not uncommon for conclusions to be jumped to and opinions voiced right or wrong. I am not always right but I will find out why when I am wrong and will laugh at myself for being a ********. Humble works and is usually a good path.

Back on topic of thread, when the header gets back from the machine shop, I'll install it and dyno test it for all to see and draw their own conclusions.

Peace to ya'll

Thanks to Paul at Mazmart for the help with R&D, a stock manifold and OBX header are on the way to the machinist. Because of the holidays, he won't have it till Wednesday but will turn it around pretty quickly. It does not look like too big a deal to do given the right equipment and know how. I'll update when more info is available.

When I do dyno, the plan is to test with Racing Beat cat back first followed by the titanium JIC.

Awesome - thanks for the update on this one. On a side note while we wait, I noticed your current dyno numbers look interesting. Are these SAE corrected?

Marietta 8

Yes the numbers are SAE corrected. I have made over 40 pulls on the same Dynojet Dyno since i bought the car in August of 03. Having seen many other 8's dynoed on the same equipment, the general consensus is that I managed to get my hands on a really good one. The car has been responsive to all changes, good or bad. I had the recalls done so I am currently on "r" calibration. I'll do a new baseline to before any other testing is done. Thanks for the enthusiasm Nemesis!

Hope you had happy Holidays you old Goober. I saw with interest that you are going to do the 1st dyno run with the rb catback. You know you will make more power with that one sooooo--I will buy that titanium one from ya. Dont mind helping you out like this.

Any updates?

Marietta 8

spoke with machinist tonight and was told that he would have it done and out by the weekend. I've got girlfriend payments to make this weekend since we spent last weekend at Road Atl so it will not get installed this weekend. Hopefully sometime in the week before Christmas (can I say Christmas? Christmas, Christmas, CHRISTMAS!!!!) otherwise it'll go on and be tested sometime between Christmas and New Years while the shop is CLOSED and I am enjoying TIME OFF. woo hoo, thanks for you patience and interest. The machine shop has set up tooling for this operation if anyone else wants to do the same when we all find out whether any good comes of the OBX Header.

nhk

Coool.. can not wait for the results.

lazi

i wanna see numbers!. hurrryyyyyyyyyy

toca

well the exhaust thing was proved wrong by turboxs they got members cars on here and made 21 whp 8 wtq with there header back exhaust so maybe rb found a way to make the 7 to 8 whp ou tof the header

ddub

No offense, but who are you to say they are ther single most "experienced" and "honest" rotary shop in the country? That is your opinion and you are entitled to it, but just because you say they are the most experienced, doesn't make it true and wont make me believe it.

I say what I say because I have met someone that used to work with Racing Beat in the beginning. I've talked to him in length about how he used to race many early rotary vehicles professionally. He used to have custom housings, irons, rotors, etc built.

In the mid to late 70's he worked with the guy that started RB. They used to trade ideas, discuss future things they wanted to try, etc. In the end, that guy at RB ended up stealing his designs and giving him no credit. The guy that started RB still has not to acknowledge that this person ever worked with him in any way, but that's another story.

This guy I know ended up quitting the racing scene because it almost bankrupted him. Now he's here in Washington as an Auto Tech teacher and happy doing it.

I believe what I believe, and say what I say, based on talking to him. However, that is not all. I've talked to a lot of other people that have worked with RB over the years and almost all of them say RB ends up screwing them over.

So anyways, you're entitled to your opinion, and I'm entitled to mine. But I in no way think RB is the most experienced rotary shop, let alone honest.

thought this thread was about the obx header?????

Exactly. So I am reposting so that my question does not get mired in the above thread hijack.Thanks in advance for your considerate consideration.

Can we get back to the OBX header? Could maybe we take this RB discussion to its own thread? WOuld you like me to start it for you?

Marietta 8

Mean people suck, nice people swallow. I'll let ya'll know when it's in my hands and again when it's on the car.

carbonRX8

iTrader: (1)

Ok, now that that is out of the way. Could you guys answer my OBX header related question that I posted a few posts back. I actually need some advise so that I can install this header on my RX8, which I am proud to say totes several RB products (and will tote more in the future).

carbonRX8

iTrader: (1)

Again...

jenkins-crew

So, about that header?

TeamRX8

iTrader: (25)

you could make an external air injection header from stainless tubing with a flange for the OE mounting connection.

Xyntax

Yeah, WTF?! I click on this thread expecting to read about the header and all I find is pussies crying over unrelated ****. You might as well talk about politics, gay sex, and religion here to finish it up. Do us all a ******* favor and

STFU NOW
